The length of line segment AB by observation if the diagram in the task content is; 14.
<h3>
What is the length of line segment AB?</h3>
It follows from the task content that the line segment MN can be considered as parallel to line segment AB. This follows from the fact that the vertices of triangle MNO are midpoints of the line segments of triangle ABC.
Consequently, it can be concluded that line segment AB is twice the length of line segment MN and hence, BC = 2 × 7 = 14.

So, M=((−2)+(6)/2,(5)+(−9)/2=(2,−2)
Answer: M=(2,−2)
Ok, so I’m guessing that 35% is $140 and that the question is asking to find the total at first.
Basically,
35% -> $140
So we’re gonna find 100%
1%->140 divide by 35 which is 4
100%-> 4 x 100= $400
And that should be your answer:)
Answer:
I think its 300
but wouldn't that be like a 2 digit number like 30? scince they are only 10 blocks 10 + 10 + 10 (3×10= 30)
If you dont understand just coment.

Answers:</h3><h3>x = sqrt(10)</h3><h3>y = sqrt(5)</h3>
============================================
Explanation:
Naturally I start with x as that letter precedes y in the alphabet; however, it's easier to start with y because it is a leg of this triangle. We will then use the value of y to find x later.
For any 45-45-90 triangle, the two legs are the same length. So that's why we're able to quickly see that y = sqrt(5)
To get the hypotenuse, we multiply the leg length by sqrt(2). This trick only works for 45-45-90 triangles.
hypotenuse = leg*sqrt(2)
x = sqrt(5)*sqrt(2)
x = sqrt(5*2)
x = sqrt(10)
The rule I used is sqrt(a)*sqrt(b) = sqrt(a*b)
----------------
An alternate path is to use the pythagorean theorem to find x
a^2+b^2 = c^2
(sqrt(5))^2 + (sqrt(5))^2 = x^2
5 + 5 = x^2
10 = x^2
x^2 = 10
x = sqrt(10)
